Bleach follows the adventures of a teenager Ichigo Kurosaki, who obtains the powers of a Soul Reaper—a death personification similar to a Grim Reaper—from another Soul Reaper, Rukia Kuchiki. His new-found powers allow him to take on the duties of defending humans from evil spirits and guiding departed souls to the afterlife, and set him on journeys to various ghostly realms of existence.
